lukasb··on What 'Project Hail Mary' teaches us about the PlanetScale vs. Neon debate
Except: "The active time includes periods when the database is receiving requests and for a duration (default 300 seconds) after the last request is received. Following this period of inactivity, the database scales down to zero, effectively pausing compute time billing."

So if you get at least one request every five minutes, neon will charge you for 24 hours of compute a day.

lukasb··on Ask HN: What Are You Working On? (June 2025)
Daily journaling + task management with native apps, sync, and fun composable semantic Excel-like formulas. Email in profile if you're interested.

"both the English and Hebrew are the only usage-standard constructions for when the verb is shooting and the object is a crowd"

"you can read the Hebrew Wikipedia page about, like, 2017 Las Vegas shooter Stephen Paddock and see that is says Paddock 'ירה לעבר' the crowd"

lukasb··on The Princeton INTERCAL Compiler's source code
I always associated INTERCAL with COME FROM but it turns out that was "invented" separately (although its first implementation was in C-INTERCAL.)

Given LLMs' OOD performance the parrot metaphor still looks good to me
lukasb··on Show HN: Kahuna, the IndexedDB-Manager Webextension
Awesome! Using IndexedDB with Dexie has been great* but I've been wanting something like this.

* Although this iOS bug could be a deal breaker, have only run into it once in pre-launch testing but pretty terrifying: https://bugs.webkit.org/show_bug.cgi?id=277615

lukasb··on Overengineered Anchor Links
In my app the user could have an arbitrary number of long documents open on mobile at the same time, vertically stacked. (This UX makes sense for my app because most docs are daily journal entries.) Sticky headers are very useful here.

Now I’m just waiting for scroll-timeline or scroll-state to hit GA so I can shrink stickied headers in pure CSS.

lukasb··on Ask HN: What are you working on? (March 2025)
Daily journaling app, Markdown format, with Excel-like composable formulas (find, ask, etc.) Email in my bio if you want to be an alpha tester.
lukasb··on Amazon to kill off local Alexa processing, all voice requests shipped to cloud
It is more complexity than just "ship everything to an LLM and use tool calls", but the payoff - perfect behavior, along with offline support, for your most common inputs - is worth it I think.

I disagree about things being less consistent. Let's imagine a 100% LLM world - in this world, you use a bunch of training to try to get the LLM to match your hardcoded responses for common inputs. If you get your training really right, you get 100% accuracy for these inputs. In this world, no one is complaining about consistency! So why not just hardcode that behavior?

lukasb··on Amazon to kill off local Alexa processing, all voice requests shipped to cloud
I don't understand why Alexa/Siri etc don't just keep their hardcoded rules for things like "set an alarm" and only ship things to a cloud LLM if they don't match a rule.
lukasb··on Beyond Diffusion: Inductive Moment Matching
Yeah I guess progressive refinement is limited in quality by how good the first N iterations are that establish the broad outlines.
lukasb··on Beyond Diffusion: Inductive Moment Matching
"Inference can generally be scaled along two dimensions: extending sequence length (in autoregressive models), and augmenting the number of refinement steps (in diffusion models)."

Does this mean that diffusion models for text could scale inference compute to improve quality for a fixed-length output?

lukasb··on Show HN: TypeLeap: LLM Powered Reactive Intent UI/UX
I 100% agree that grafting a chatbox on an existing app that wasn't meant for it sucks. (I'm working on an AI app where I set a "no chatbox" constraint, see my profile.)

However, I think a lot of people are willing to type if it will do something useful they can't otherwise accomplish. And: typing gives you user intent, very valuable.

lukasb··on Mistral OCR
Even assuming you could get people to do the work (probably the real issue here) could a single schema syntax capture the semantics of the universe of documents that exist as PDFs? PDFs succeeded because they could reproduce anything.
